.man T. FLYNN, or son Francisco, waronnm .same-may' be constructed to withstand xceptionally great lateral stresses, which can be constructed with the consumption of a relatively small amount of concrete and at a relatively high rate of speed.

Another object of the invention is in the provision of walls which are peculiarly adapted to the construction of tunnels, or the'like, in earth which is permeable toV water or in situations where a tunnel is partially or entirely submerged in water, for example, infthe bed of a river. y f The invention consists in the employmen of .a dual-wall, which may or maynot be v.

formed of an i gregation of blocks, which are connected by posts and tie-bars to form 21 rlgld and stable structure' with a spacebetween the wall parts foi the reception of',a filling suitable to the service obtaining with the varied applications. AThe invention further consists in the novel Construction and combinati-on of .the wall elements, as will be hereinafter described' and claimed. i

Fig. 4 is a vertical section ofa portion of apile? nieinberadapted for use in carrying out the inventlon. v v p '1 he numeral 5 designatesa footing or sill which is formed of a plurality of concretev blocks, as 6, or a homogeneous mass of concrete which is deposited andpermitted-to solidify in place. This footing 1s of a width to support an inner wall part Tand an outer wall part 8 and may extendbeyond one or both of these parts, as at 5', to furnish a Specification 'of Letters Patent.

large `base-area to'sustain such superstructure'.

-As illustrated in Fig.- l the aforesaid wall parts are severally 4comprisedof aplurality of blocks, for instance, like that shown in Fig'. Said blocks are formed with oentra1ly`disposed apertures 10, and arecess 10 at each end 'wherethrough are extended previously driven piles'll. A recess 12 is provided in the top face lof a block concentrically of the aperture 10 andthence extending, as at 12-, rectangulaily to a side face. The

purposeof these recessesfis to" furnish housings for the ends of tiebars 13l which unito the piles of one ofthe wall parts with those i-n the otherrpart and are accordingly provided with eyes 13 to receive the piles. The tie-bars in the footing 5, as shown in the view, may if sodesired, be embedded therein.

In Fig. 4 'I illustrate the preferred form of pile consisting of a tubular member provided at its lower end with a `driving point 15 which is formed with an' internal socket ably providedwith perforations 11'.

by4 The pile is desir- According to my conception, the manner of constructing a wall would be as follows:

The piles are first driven in suitable spaced relation with each other and t a depth Sudicient t-o reliably hold them in uprl ht -positions. The footing, as with bloc s, are then lowered upon thev piles to seat in a natural or prepared bed of the body of water, as with a sea-wall; and then are successively laid upon 'the footing a tier yof blocksfor both of the wall parts by lowering theV same upon the appropriate piles 11. The tie-bars 13 are then placed over couples of the piles and lowered to find seats in the recesses 12-12l therefor. The blocks to form the tier next above are then lowered, followed by tie-bardas above described,l and so on alternating the blocks and bars until the wall parts have been raised to a sufficient height. mixture of hydraulic cementl` and water is now poured into the tubular` piles `and from such of it asl exudes through they perforations a bond is made between the piles and the incasing Wall parts'andthus completes a wall structure with a space 16 between its aforedenominated inner and outer wall parts. vThisspace should be lle'd with a ballast of some heavy material, `such as gravel, or of a puddling having an advention, is the practicability of constructingv a wall or tunnel in under-Water situations; the strength and rigidity-of the structure,

due to the reinforcing of the various co-` operating elements; and in the( comparatively low cost withwhich the wall can be constructed.

Having described my invention, what I claim, is-

l. In a structure of the class described, the

combination with the wall parts and the supporting footing therefor, of perforated tubular piles inclosed by both the wall parts and said footing.

2. In a tunnel, a two-part concrete wall supported by a footing common to' both parts, erforat'ed tubular piles inclosed by each o said parts and extending through said footing, and tie-bars connecting said piles in couples. A

3, A tunnel having an. arched roof, a bottorn footing, two-y art walls with a space between the parts o each wall, piles extending through the respective parts of each said wall, and a concrete filling for said spaces.

Il. A tunnel having an arched roof, a bottom footing, two-part walls with a space between the parts of each wall, piles extending through the respective parts of each said wall, connecting tic-bars coupling the piles of the partsof each such wall, and a concrete {illin for said space.

5. In a structure of the class described, the combination of two Wall-parts, a :footing serving to support both of said wall-parts, andpiles dis osed at intervals throughout the lengths o said Wall-parts and extending therethrough and also through said footing.

6. In a structure of the class described, the combination of two 'wall-parts, a footing' serving to support both of said wall-parts, piles isposed at intervals throughout the lengths of said wall-parts and extending therethrough andalso through saidvfooting, and tie-bars coupling individual piles of one of the wallparts with individual' piles of the other of such parts.

7. In a structure of the class described, the combination of i two wall-parts lseverally formedof block elements, a footing serving to supportboth of said wall-parts, perforated tubular piles disposed at intervals throughout the lengths ofv said wall-parts and extending through said elements and also through said footing, and tie-barsA coupling individual piles of one of the wall-parts with individual piles of theother of such parts.

8. In a structure of the class described, the

ncombination of two wall-parts severally formed of block elements, a footing. serving Vto support both of said wall-parts, and periles disposed at intervals forated tubular throughout the engths ofsaid Wall-parts and extending through said elements and also through said footing.

9. In a structure of the class described, a

ywall comprised of perforated tubular piles arranged in.v two parallel rows, concrete foot members through which the piles of both said rows extend, concrete blocks supported by said foot members and arranged as walls in line with and inclosing the respective rows of piles, tie-bars adapted tol couple the piles of one of said rows with the piles of the other row and extend across the space intervening the rows of said blocks.
